What does the gradient
of a distance-time
What is the speed of the object shown in the first section of this distance-time
- 5 m/s
- (It travels 10 meters in 2 seconds)
What is the difference between speed and velocity?
- Speed just has a size
- Velocity has a size and a direction (a vector)
What does acceleration mean?
How quickly the velocity of an object changes
What does the gradient of a velocity-time graph represent?
How can you calculate distance travelled from a velocity-time graph?
- Calculate the area under the graph
